InLinks
InLinks Optimization Ltd — the entity-based SEO company that maintains entitymap (via Waikay) and ships its one reference implementation, the Waikay EntityMap Generator. The standard was initiated by Fred Laurent with support from Dixon Jones; neither is paged separately, since the homepage is the only evidence held for them.
Worth recording because it locates the proposal: entitymap is published by a vendor whose product is entity optimization, which is both why the standard exists in usable form and why its adoption claims need outside corroboration. See structured-data-for-ai for the evidence problem this cluster shares.
